2 Claims. (Cl. 60-97) This invention relates to new and useful improvements in pressure operated apparatus for imparting reciprocating and/or oscillating motion to apparatus, machines, and devices of all kinds.

The principal objects of the invention are directed to the provision of apparatus which is constructed and arranged to impart reciprocating and/ or oscillating motion or power independently or simultaneously, as may be desired.

The apparatus is adapted for use in connection with machines and apparatus and devices of various and numerous types, where it is desired that a component or components receive a reciprocating or oscillating force or both, and for such purposes, its function is such that it may be termed a motor.

In a general way, the novel apparatus of the invention embodies a drive member which is reciprocable and oscillatable in opposite directions and may be connected to various machines or devices, or which may have various devices or components secured thereto.

One of or opposite ends of the drive member may be conveniently and easily connected to a component or components of an apparatus or machine to which it is desired to impart motion or power.

The reciprocations and oscillations of the drive member of the motor are controlled by pressure, which may be air pressure, or liquid pressure or the like, and may be connected to the sources thereof. The pressures may be controlled by any desired form of valve or pressure control devices in the connections between the sources of pressure and the motor.

It is not desired to be limited to the form of motor shown and described as various changes and modifications may be made therein without departing from the spirit and scope of the invention.

In the drawings:

Fig. 1 is a longitudinal sectional view through a motor embodying the novel features of the invention; and

Figs. 2, 3, 4 and are transverse sectional views on the lines 22, 33, 4-4, and 5-5 respectively of Fig. 1.

Referring now to the drawings more in detail, the novel features of the invention will be described.

An elongated shell 2 is provided, which is in the form of a metal tube. A forward cap 4 is disposed in the forward end of the shell and a rear cap 6 is disposed in the rear end of said shell.

Intermediate opposite ends of the shell, there is a bulkhead 8. An elongated divider 10 within the shell extends between the forward cap 4 and the bulkhead 8.

The caps 4 and 6, bulkhead 8, and divider 10 may be secured against displacement in the shell by any number of screws, such as 12, as indicated in Fig. 3.

A sleeve 14 is oscillatable in a bushing 16 of the cap 4, and in bushings 18 and 20 of adjacent inner ends of the cap 4 and bulkhead 8 respectively.

A drive member 22, in the form of a rod, is reciprocable in the bulkhead 8 and cap 6, and bushings 24 and 26 of the bulkhead and cap 6 respectively are provided therefor, as shown.

The forward end of the drive member 22 is squared at 28 and the outer end of the sleeve 14 has a square bore slidably receiving said end 28 of the rod. The rod may reciprocate relative to the sleeve. As the sleeve 14 oscillates, the rod 22 is oscillated thereby.

Either one or both ends of the drive member may be connected to components of apparatus or machines to impart reciprocatory or oscillatory motion thereto.

The divider 10, which is secured within the shell 2, is shown in Fig. 2, and functions as a wall circumferentially of the shell in the space between the end cap 4 and bulkhead.

A vane 30 is secured to the sleeve 14 and extends between adjacent ends of the cap 4 and bulkhead 8.

Said vane may be of any form but, for purposes of disclosure, comprises a plate 32 fixed to and depending radially from the sleeve, and a plate 34 which clamps an elongated yieldable member 36 to the plate 32. Screws, or any suitable means, may secure the plates together with member 36 therebetween. The member 36 will be of such material as to wipe on the shell and act as a seal in oscillations of the sleeve 14.

An opening 38 provided in the cap 4 is shown as tapped. A passageway 40 extends longitudinally rearwardly in the divider from the opening 38 to a circumferentially extending passageway 42 of said divider, see Figs. 1 and 2.

A similar opening 44 of the bulkhead 10, see Fig. 3, is in communication with a forwardly extending passage 46 of said bulkhead which communicates with a forwardly extending passage 48 in the inner rear end of the divider. This passage 48 terminates in a circumferential passage 50 of said divider similarly to the passageway 42 therein. Pressure from the passageways 42 and 50 conduct pressure to the sides of the vane 30.

Openings 38 and 44 may be connected by piping to a source of pressure, such as air pressure, should that be desired. Valve means in the connection will be arranged to control pressure and the discharge thereof to and from the said openings so that the sleeve 14 may be oscillated in either direction and through a predetermined angle by manipulation of the valve means, all, as may be desired.

A piston 54 is reciprocable in a rear space of the shell 2 and is rotatably mounted on the drive member by anti-friction bearings 56. Inner races of the bearings are held on the drive member by snap rings 58 in grooves provided therefor. Other snap rings, such as 60, in outer ends of the piston, hold outer races of the bearings 56 against displacement axially.

The bulkhead, towards its rear end, is provided with a radial pressure passage 62, see Fig. 4, which is in communication with a passage 64 extending axially of the motor into the rear space.

The rear cap 6 is provided with a radial opening 66, as shown in Fig. 5.

The openings 62 and 66 may be connected by piping to a source of pressure, which may be air or hydraulic pressure. Valve means, associated with the piping, may be manipulated for delivery of pressure at one end of the rear space and discharge at the other end thereof so that the piston and drive member may be reciprocated in the desired direction.

The axes of the pressure openings for the forward space between the forward cap and bulkhead, in which the vane of the sleeve is disposed, may be at any desired relative angle. Likewise the openings for the rear space in which the piston is disposed may be at any angle.

The bushings 18 and 20 are provided with sealing or packing means 68, the bulkhead 8 with similar means 70, and the piston with packing means 72. Sealing or packing means 74 is provided in the cap 6 for the drive membe Sealing means 76 is provided around the piston. Sealing means 78 is provided between the sleeve and the bulkhead 3,. and around caps 4 and .6.

' Rings 80 lock the shell to the caps 4 and 6, and to the ulkhe d 8.

The sealing and packing rings referred to may take form desired and may be formed of various materials. rings formed from yieldable or resilient rubber like material have been found to be entirely satisfactory for the practise of the invention, but it is not desired to: be limited thereto.

One or both of the end caps may be externally threaded or otherwise formed to facilitate securement of the motor tomac hines or apparatus or for securement thereto of vari u de i e The apparatus is adapted for broad application where it isjdesired to impart reciprocating and/or oscillatory motion to parts or components and, by controlling pressure to the oscillating vane or reciprocating piston, it is possible to impart motion within fine limits over a range of operation.

Various changes and modifications may be made in the form of the motor without departing from the scope and spirit of the invention, it is therefore desired to be limited, ifat all, by the appended claims rather than the foregoing description.
